Bassmasters are always better as guitar amps.

SPECIFICATIONS:
These amps used 6DQ6A valves, giving them a unique tone. These valves were
commonly available in Australia than valves used in imported amps as they
were used in black and white tv sets. Rola supplied the single 12" speaker.
They were specially made for bass use and are 12" diameter and 7.5" deep.
Almost twice the depth of a 12P and weighed around 4Kg. Code 12UEG, E for
electric, G for guitar and the combination of these speakers and valves make
these combo amps much sought after today.
